AfterVideoPreviewFetchedEvent
New in version 12.2
The purpose of the PSR-14 event
\TYPO3\
is to modify the preview file of online media previews (like YouTube and Vimeo).
If, for example, a processed file is bad (blank or outdated), this event can be
used to modify and/or update the preview file.
Example
Registration of the event listener in the extension's Services.:
services:
# Place here the default dependency injection configuration
MyVendor\MyExtension\Resource\EventListener\MyEventListener:
